no answer

I reported my ADSL down beginning December waited an hour and a half no answer, again January and waited for ever for them to answer, put the phone down after over an hour sent a report on yellow peter, then they got back to me, now again on the phone for almost 2 hours,then put the phone down, your service is shocking, like I said before hire more staff, waiting 20 minutes on a phone is unacceptable, you need to do something about it, can you please get someone to call me to sort out my problem tanks
